BUNG-LOCK.

SPECIFICATION forming part of Letters Patent N0. 772,516,.dated. October 18, 1904. Application filed December 15, 1903. Serial No. 185,285. (No model.)

To all whom, it may concern: 7

'Be it known that I, HERMAN JAHN, a citizen of the United States, residing at Chicago,

. shape and of any suitable material.

in the county of Cook and State of Illinois,

have invented certain new and useful Imaprovements 1n Bung Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable, others skilled in the art' to which it appertains V lock embodying my improvements, the bung beingshown in place in the bung-holderbf a cask. Fig. 2 is a side elevation showing the bung-lock in position to enable the bung'to be placed in or taken holder of a cask. 7 p

The bungl may be made of anysuitable On its inner end it is provided with a slot 2, which ishere shown as extending across the'sarne and of suitable depth. In connection with the bungI employ a locking device 3, of which two are here shown for locking opposite sides of the bung. Each of the locking devices out from the bungcomprises a stem 4i, mounted for revolution and for longitudinal movement in the opening 5 in the bung, which extends from the slot 2 to the outer end of the hung, the said stem being of suitable length to extend entirely through the bung and to project for some distance from the outer end thereof. At the inner end of thelocking-stem is formed a locking-arm 6, here shown as disposed at right angles thereto. Anoppositely-extending arm 7 is attached to the outer end of the stem, and on the projecting portion of the latter is a coiled extensile spring 8, which bears between the outer end of the bung and the arm- 7, and the latter has near its free end an eye or opening 9. Before inserting the bung or withdrawing thesame the stem 4: must be pressed inwardly against the tension of its spring '8 to'ca use the locking-arm 6 to'clear the slot 2, and the said stem must be turned by means-of the said arm 7 to cause the locking-arm 6 to be disposed within the radius of the smaller end of the bung,as shown in Fig. 2. When the bung is in place in the bunghole, thestem is turned-to project the locking-arm Gradially from the bung, and the tension of the spring 8 causes the stem 4: to move outwardly, so that the locking-arm 6 is drawn into the slot 2, caused to. engage the inner side of the cask, a section of which is indicated at a in Fig. 1, and the said spring maintains the said stem in such position. Where two of the locking. devices are provided forthe bung and the same are thus engaged, the turning of the stems to the required position to project the locking-arm 6 radially from the bung'causes the arms 7 to come in contact with each other, so that their eyes or openings 9 register with each other,

and a wire, cord, pin, or other suitable device may be passed through the said registering openings to lock the said arms 7 together, as willbe understood. 7

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various'changes in the form, proportion, and theminor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure'by Letters Patent, is-

A bung having a transverse slot at its inner end and longitudinal openings extending from said slot to its outer end, longitudinally-movable and revoluble locking-stems in said openings, having each a locking-arm at its inner end adapted to enter the slot and project lat- In testimony whereof I have hereunto set erally from the bung, and an oppositely-exmy hand in presence of two subscribing wit- 1O tending arm 7 at its outer end, said arms 7 of nesses. the respective stems being adapted to engage 5 each other When the locking-arms are projected from the bung, and springs to move Witnesses:

the locking-stems outwardly, substantially as MCKENZIE GLELAND, described. Russ L. PHELPS.
